A new desalination method produces drinking water from seawater without chemical additives.
The solar-powered system uses specially engineered black metal to absorb sunlight.
Its self-cleaning surface separates and collects salts, instead of dumping them as harmful brine waste.
From the salts, the system can extract lithium, a key material for rechargeable batteries.
The approach could help address global water shortages and growing mineral demand.
The United Nations estimates that 2.2 billion p
